I think I've tried all the options from the various man pages and tutorials, but still get login failed. I always use psql, but wanted to see how this front end looks like.
Running on OpenBSD 4.3 macppc

I did that too, really, and looked at them all (until page 10+), but still cannot work it out (also, the sourceforge page does not open).
Sometimes I feel quite stupid, I'll better look at it when I'll be less tired.
Thank you anyway.

I was just being silly, but the very first hit is the phppgadmin FAQ, and the first question in the FAQ tells you that you must compile PostgreSQL support into PHP, or bring it in as a dynamic pgsql.so extension.

Since you hadn't provided any information, I don't know if this applies or not. Does it?

oh well I don't know...
I installed both from the packages and then followed these instructions:

Code:

php5-core-5.2.5p2: complete
php5-pgsql-5.2.5: complete
phpPgAdmin-3.5.5p0: complete
--- php5-core-5.2.5p2 -------------------
To enable the php5 module please create a symbolic
link from /var/www/conf/modules.sample/php5.conf
to /var/www/conf/modules/php5.conf.
ln -s /var/www/conf/modules.sample/php5.conf \
/var/www/conf/modules
The recommended php configuration has been installed
to /var/www/conf/php.ini.
Don't forget that the default OpenBSD httpd is chrooted
into /var/www by default, so you may need to create support
directories such as /var/www/tmp for PHP to work correctly.
--- php5-pgsql-5.2.5 -------------------
You can enable this module by creating a symbolic
link from /var/www/conf/php5.sample/pgsql.ini to
/var/www/conf/php5/pgsql.ini.
ln -fs /var/www/conf/php5.sample/pgsql.ini \
/var/www/conf/php5/pgsql.ini
--- phpPgAdmin-3.5.5p0 -------------------
The phpPgAdmin has been installed into /var/www/phpPgAdmin
You should point this to the DocumentRoot of your web-server:
# ln -s ../phpPgAdmin /var/www/htdocs/phpPgAdmin
(make sure you use a relative symlink since Apache is chrooted)
You can ensure you have a working install by accessing:
http://<localhost>/phpPgAdmin/index.php
You need to modify /var/www/phpPgAdmin/conf/config.inc.php according
to your database(s) settings

got in, I had to edit /var/www/phpPgAdmin/conf/config.inc.php (I pointed to my local ip)
Only, once in, I cannot use it, because I'm cursed with a mac ppc, and there is no java support for this architecture, and the web page to browse my database uses javascripts.
Actually, this is a question I long wanted to ask: why most web pages now are full of javascripts? And why is it what without it you cannot browse the web page? Are they things html cannot do? Sorry if it's a bit out of topic.

...because I'm cursed with a mac ppc, and there is no java support for this architecture, and the web page to browse my database uses javascripts.

Don't equate Java with JavaScript. They aren't the same.

Netscape originally came up with JavaScript (which syntactically does not resemble Java at all....) as a scripting language available in their browser which everyone later emulated. JavaScript is so ubiquitous today that it has been standardized under the name ECMAScript. Java does not have to be installed on a client machine in order for a browser to use JavaScript.

oh well, I really need to study.
But I came to that conclusion because everytime I have problems with web pages it's because of javascripts. And this happens both with firefox and kazehakase (more with firefox, really, which crashes often). I never had this problems when my old notebook still worked (i386). But probably from what you say I'm using a lot of javascripts without noticing it, and the problem is another alltogether.
Now with phpPgAdmin I can login, and when I login I get again the login page but this time in all the three frames, if I login in the left one, I get the tree of my database, clicking on one of the databases brings me back to the login prompt (in the small frame), an guess what, the tree is in javascript.
So, I guess I'm cursed with something else...

yeah, nothing to do with JavaScript really, I should say sorry to JavaScript.
Maybe the problem with phpPgAdmin is still a misconfiguration of mine.
As far as Firefox goes, I'm still running 4.3 because the ati driver of 4.4 for ppc is broken (remember?), but 4.4 has Firefox 3 (here is 2) which might be fixed.
Actually, I'm missing a lot w3m which is not ported to ppc. I wish I could help. but as you see from my questions I'm very far from that goal...
Thanks a lot anyway
